Harkening back to the early years of analog synthesizers, Moog's Grandmother has the characteristic style of a vintage synthesizer from the past. But make no mistake; this all-analog semi–modular instrument is 100% ready for the future. With a design focused on pure synthesis, you'll appreciate the immediacy of just getting on and designing sounds. There are no presets, no recall, what you see is what you get, leading to a lifetime of creative sound exploration. Grandmother's sound engine, modulation engine and onboard spring reverb tank are 100% analog. There are no menus, nothing to get in your way of creating your own unique sounds.

Grandmother’s semi-modular design means you can start playing immediately without the need to manually patch and route any signals. But should you want dive deeper into creating more complex sounds, Grandmother features 41 individual patch points that will override the internal wiring, leading to expansion possibilities that are only limited by your imagination. Even if you’re only familiar with the basic building blocks of an analog synthesizer, the Grandmother welcomes an experimental approach that can turn into incredibly inspiring sounds. In addition, the 21 inputs, 16 outputs and a parallel-wired 4-jack mult, can be used to expand the Grandmother into a larger Eurorack ecosystem, or is the perfect patch point to integrate with Moog Mother-32 or DFAM semi-modular synthesizers.

Moog Grandmother Semi-Modular Synthesizer

All analog, start to finish

Grandmother has the essential tools you need to get started, with some added extras. There are two analog oscillators built-into Grandmother, each with selectable triangle, sawtooth, square and pulse waveforms, and a hard sync button capable of creating some very complex timbres. The analog LFO is capable of reaching audio rates, acting as a third oscillator that can develop into some really aggressive tones. Also onboard is a classic Moog Ladder filter with a range of 10Hz – 20kHz, a patchable 1-pole high-pass filter, and an analog ADSR envelope generator ready to sculpt your sound.

Diving deeper

The team at Moog thought of everything here. Knowing that most sound designers would use a spring reverb effect on a synth of this nature, they’ve gone ahead and added an onboard analog spring reverb tank capable of processing internal and external sounds. It’s a welcomed addition, with the ability to add some darker tones or tame any intense frequencies. Grandmother also features a built-in arpeggiator and an onboard sequencer that can store up to 3 sequences with up to 256 notes each. Add this to your Eurorack ecosystem and you’ll have full control over all of your modules.

Moog Grandmother Semi-Modular Synthesizer

Classic feel, current mood

Even though Grandmother is every bit retro in design, it features some modern-era additions that take this synth from a thing of the past into an instrument for the future. As for connectivity, the Grandmother has everything needed for today’s production environment including a 5-pin MIDI In/Out/Thru as well as MIDI over USB for instant integration with your host computer. There’s also both a 1/4” main output and a 1/4” external audio input that’s capable of taking in signals from guitars, drum machines and more. Grandmother can route these audio sources through its signal chain, imparting classic Moog character at every step along the way, including its spring reverb tank, and spit them back out again. Grandmother's 32-note premium Fatar keybed makes this a premium standalone synth but will also work perfectly as the front end to an existing modular system. No matter how you decide to use it, Grandmother will give you a lifetime of sound exploration.
